Resource Use and Clinical Outcomes in Infants with Supraventricular Tachycardia Monitored with the Owlet Smart Sock.

OBJECTIVES: To describe the prevalence of Owlet Smart Sock (OSS) use in infants with supraventricular tachycardia (SVT) and associated demographic and clinical characteristics of users and to analyze the association of OSS use on medical resource use and clinical outcomes from emergency department (ED) encounters for SVT. STUDY DESIGN: This was a single-center, retrospective cohort study of infants with confirmed SVT from 2015 to 2022. OSS users and nonusers were compared across clinical and demographic parameters. Medical resource use (phone calls, office visits, ED visits) and outcomes (need for intensive care, length of stay, echocardiographic function, clinical appearance) were compared between OSS users and nonusers. RESULTS: Of 133 infants with SVT, OSS was used by 31 of 133 (23%), purchased before SVT diagnosis in 5 in 31 (16%) of users. No demographic difference was found between OSS users and nonusers. OSS users had more phone notes than nonusers, (P = .002) and more ED visits (P = .03), but the number of office visits and medication adjustments did not differ. During ED presentation, OSS users had better preserved left ventricular ejection fraction on echocardiogram (P = .04) and lower length of hospital stay by a mean 1.7 days (P = .02). CONCLUSIONS: OSS is used by a portion of infants with SVT. It is associated with more frequent phone calls and ED visits but lower length of stay and better-preserved cardiac function upon presentation.

mRNA Coronavirus Disease 2019 Vaccine-Associated Myopericarditis in Adolescents: A Survey Study.

In this survey study of institutions across the US, marked variability in evaluation, treatment, and follow-up of adolescents 12 through 18 years of age with mRNA coronavirus disease 2019 (COVID-19) vaccine-associated myopericarditis was noted. Only one adolescent with life-threatening complications was reported, with no deaths at any of the participating institutions.

Social Risk Factors Impact Hospital Readmission and Outpatient Appointment Adherence for Children with Congenital Heart Disease.

OBJECTIVE: To examine the relations of individual and cumulative social risk factors to hospitalization outcomes and adherence to outpatient cardiology appointments within the first 2 years of life for congenital heart disease survivors. STUDY DESIGN: Data were extracted for 219 patients who underwent infant cardiac surgery with cardiopulmonary bypass. Cumulative social risk was dichotomized into high social risk (≥2 risk factors; n = 103) versus low social risk (≤1 risk factor; n = 116). The risk of morbidity by procedure was assigned from 1 to 5 (Society of Thoracic Surgeons and European Association for Cardio-Thoracic Surgery Morbidity Scores and Categories). Two-way ANOVAs examined the effects of social risk and morbidity risk on length of first surgical hospitalization, number of readmissions and readmission days, subsequent cardiac surgical interventions, and adherence to outpatient cardiology appointments. RESULTS: An interaction between social risk and morbidity risk was identified for number of readmission days, F(4, 209) = 3.07, P = .02, η2 = .06. Pairwise comparisons demonstrated that, among those patients with the lowest risk of morbidity by procedure (morbidity scores of 1 and 2), patients at high social risk had more readmission days than patients at low social risk (morbidity score 1: 16.63 ± 34.41 days vs 3.02 ± 7.13 days; morbidity score 2: 27.68 ± 52.11 days vs 2.20 ± 4.43 days). High social risk also predicted significantly worse adherence to cardiology appointments. CONCLUSIONS: Cumulative social risk impacts readmission days for patients with congenital heart disease with a low risk of morbidity by procedure. Social risk assessment can identify families who may benefit from social/behavioral interventions to optimize discharge readiness, congenital heart disease home management, and long-term outcomes.
